Effect of sublethal concentrations of four chemicals on susceptibility of juvenile rainbow trout (Oncorhynchus mykiss) to saprolegniosis.

The effects of propolis on gill, liver, muscle tissues of rainbow trout (Oncorhynchus mykiss) exposed to various concentrations of cypermethrin

The aim of this study was to investigate the therapeutic effects of propolis for the toxicity of cypermethrin (CYP) on histopathological changes in tissues of rainbow trout (Oncorhynchus mykiss). CYP is one of the most toxic pyrethroids highly for the aquatic organisms. The fish were exposed to three sublethal concentrations of CYP (0.0041, 0.0082 and 0.0123 ppm). In addition, different concent...

Effect of prebiotic of Behsam on growth, feeding efficiency and and body composition of rainbow trout (Oncorhynchus mykiss) juvenile

To investigate the effect of dietary supplementation of Cell wall of Saccharomyces cerevisiae on growth performance and carcass composition of rainbow trout juvenile, an experiment was carried out on 600 pieces of Oncorhynchus mykiss with averaged mean weight 18±2 g for 45 days. This experiment conducted in a completely random design with four treatments which contain triplicates. Three levels ...

Short Communication: Effects of Hypoxic Stress on Electrolyte Levels of Blood in Juvenile Rainbow Trout (Oncorhynchus mykiss)

Effect of dietary sesame oil on growth and carcass composition of rainbow trout ( Oncorhynchus mykiss) ‎juvenile

This study investigated the effects of replacement of fish oil with dietary sesame oil (SO) on growth performance and fillet composition of rainbow trout ( Oncorhynchus mykiss) juvenile with initial mean body weight 52.54 ± 2.03 . Triplicate groups of 30 fish each held under identical culture conditions were fed twice daily by iso-nitrogenous, iso-calorific and iso-lipidic diets for 8 weeks. E...

Effects of dietary rainbow trout (Oncorhynchus mykiss) viscera protein hydrolysate on some hematological and blood serum biochemical parameters of rainbow trout juvenile

The aim of this study was to prepare rainbow trout (Oncorhynchus mykiss) visceral protein hydrolysate (VPH), determine the peptide molecular weight and using rainbow trout visceral protein hydrolysate in diet of rainbow trout juvenile to investigate its effects on some hematological and blood serum biochemical parameters. The viscera of rainbow trout were hydrolyzed by alcalase enzyme and Antio...
